Vijay Singh had one bad swing Friday, but it wasn’t enough for him to lose the lead in the rain, whipping wind and eventual sunshine at the Mercedes-Benz Championship in Kapalua, Hawaii.

Singh pulled his tee shot in the native grasses on the par-5 18th hole, hit a remarkable recovery and escaped with a par, giving him his second straight 4-under 69 and a one-shot lead over Trevor Immelman and Will MacKenzie in the PGA Tour opener.

MacKenzie had a chance to tie until missing a 10-foot putt, giving him a 70. Immelman, the Rookie of the Year in 2006, birdied two of his last threeholes for a 68.

The start of the second round was delayed 1 hour, 20 minutes because of a light rain that began overnight and didn’t stop until an hour after the round started. The trade wind picked up strength to 35 mph gusts.
